This community-led research study protocol emphasises placing black youth impacted by the legal system, their families and their communities at the forefront of substance use treatment development research and decision-making. The study, the Cultural Adaptation of a Substance Use Treatment (CAST) Project, challenges traditional top-down approaches to treatment creation, advocating for a grassroots model that centres community knowledge, values and active participation.
The CAST project is a US-based mixed-methods study with an exploratory design that examines the impact of racial discrimination on substance use in black youth impacted by the legal system. The study participants are black youth impacted by the legal system (N=15), parents of black youth impacted by the legal system (N=10) and community members who serve black youth (N=10) (total N=35 study participants). Study participants from each group (youth, parents and community members) will participate in three separate focus groups, respectively, to provide feedback on the culturally responsive content needed to best support black youth impacted by the legal system around substance use and mental health. The eight-step Assess, Decision, Adaptation, Production, Topical Expert, Integration, Training, Testing framework will be used as a guide to inform adaptations to the Motivational Enhancement Therapy and Cognitive Behavioural Therapy (MET/CBT12) for black youth impacted by the legal system. Once the cultural adaptation process has been completed, the study will conclude with an open feasibility and accessibility trial of the culturally adapted MET/CBT12 manual. The primary outcomes of this study are the feasibility and acceptability of the culturally adapted manual, measured by treatment attendance and participant feedback. Secondary outcomes include reductions in substance use and discrimination distress, and improvements in mental health symptoms.
This study was approved by the Institutional Review Board (IRB) at the University of California, San Francisco (IRB Protocol Number: 23-40126). All study procedures will be conducted in accordance with the ethical standards outlined by the institutional review board. The results from this study will be shared through peer-reviewed publications, academic conferences, community forums and policy briefs to support broader implementation of culturally adapted adolescent substance use interventions that address discrimination-related stress and substance use among black individuals impacted by the legal system.
To determine the prevalence of undiagnosed hypertension and its risk factors among adults in rural Sidama Region, Ethiopia, using a two-step diagnostic method.
A community-based cross-sectional study was conducted from 1 April to 31 July 2024. Data were collected among adults aged 45 years and above using the World Health Organization STEPwise Approach to Surveillance questionnaire. The Demographic and Health Survey questionnaire was also used to collect data on household characteristics.
Selected rural kebeles of Shebedino district, Sidama, Ethiopia.
2875 adults aged ≥45 years identified via census.
Undiagnosed hypertension was defined as systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg, in individuals with no history of the condition.
The prevalence of undiagnosed hypertension ranged from 7.7% (95% CI: 6.7% to 8.7%) to 14.3% (95% CI: 13.0% to 15.6%). The previously diagnosed hypertensive cases were found in 3.3% (95% CI: 2.7% to 4.1%). Female sex (AOR 2.02; 95% CI: 1.44 to 2.82), age ≥ 65 years (AOR 1.48; 95%CI: 1.01 to 2.15), and history of alcohol drinking and khat chewing (AOR 2.94; 95%CI: 1.52 to 5.66) were significantly associated with undiagnosed hypertension. Lack of awareness of salt-related health risks (AOR 3.14; 95% CI: 2.30 to 4.30) and no prior blood pressure measurement (AOR 5.60; 95% CI: 1.73 to 18.07) were also associated with undiagnosed hypertension.
Undiagnosed hypertension is common among adults aged ≥45 years in the rural Sidama Region. Female sex, older age, substance use, limited awareness of salt-related health risks, and lack of prior blood pressure measurement were the identified risk factors. Regular screening should be implemented to detect cases at an early stage.
The standard treatment for high-grade squamous intraepithelial lesions is excisional involving the uterine cervix, while surveillance is an acceptable approach for low-grade squamous intraepithelial lesions. There is controversy about excisional treatment on pregnancy outcomes. The objective of this study was to determine pregnancy outcomes in women living with and without HIV who underwent excisional treatment for high-grade cervical intraepithelial lesions.
This retrospective cohort study compared the pregnancy outcomes of women with and without HIV who were or were not treated for cervical intraepithelial lesions. A cohort of 488 women with and without HIV infection who did or did not receive excisional treatment for cervical intraepithelial lesions between 2009 and 2022 was enrolled. Adverse pregnancy outcomes (preterm delivery and pregnancy loss) in women with and without HIV, untreated or treated for cervical dysplasia, were recorded and analysed. The significance of the obtained results was judged at the 5% level.
The study was conducted at all Academic Model Providing Access to Healthcare-Kenya satellite sites, which offer cervical cancer screening and treatment for cervical dysplasia in western Kenya. The Moi Teaching and Referral Hospital was also included.
A cohort of 488 women aged between 20 years and 49 years, with and without HIV, diagnosed and treated for high-grade cervical intraepithelial neoplasia, and those followed up for low-grade cervical intraepithelial neoplasia between 2009 and 2022, were included.
The study was interested in adverse pregnancy outcomes, particularly pregnancy loss and preterm delivery following cervical excision treatment for high-grade cervical intraepithelial lesions.
After adjustment for confounding factors, excisional treatment involving the uterine cervix—particularly cold knife conisation—was associated with higher odds of adverse pregnancy outcomes (OR 13.1; 95% CI 1.1 to 137.1; p=0.032). A prior history of adverse pregnancy outcomes was also strongly associated with subsequent adverse outcomes after treatment (OR 37.7; 95% CI 13.8 to 102.7; p
Adverse pregnancy outcomes after excisional treatment of the uterine cervix for high-grade squamous intraepithelial lesions are multifactorial and were associated with cold knife conisation and prior adverse pregnancy outcomes, while maternal HIV infection was not independently associated with adverse outcomes.
To explore stakeholder experiences with implementing the living guideline (LG) development framework in oncology, and to identify barriers, facilitators and solutions to support its uptake and sustainability.
An exploratory sequential mixed methods design was used, beginning with qualitative semi-structured interviews with guideline development stakeholders, analysed thematically; and followed by a cross-sectional survey to quantitatively rate the importance of factors identified in phase one.
National and international oncology guideline development programmes using the LG development framework.
Stakeholders involved in LG development, including expert panel co-chairs, panel members, patient representatives, methodologists and administrative staff.
Nine stakeholders participated in qualitative interviews, and 45 completed the survey. Most participants were male (5/9:56% qualitative; 26/45:58% quantitative) and based in the US (7/9:78% and 29/45:64%, respectively). Overall, the results from both the qualitative and quantitative strand revealed seven themes (34 subthemes) as barriers and six themes (21 subthemes) as facilitators. Additionally, 9 themes were proposed as solutions. The most frequently reported barriers included evidence timeliness, interpretation and publication delays. Prominent facilitators included effective management, resource optimisation and panel engagement. Participants strongly endorsed investment in artificial intelligence enhanced tools to improve the speed and efficiency of evidence acquisition and review.
While the LG framework provides strong methodological guidance, its practical application presents notable challenges, particularly in resource demands and implementation logistics. Successful adoption requires adequate infrastructure, expertise and oversight. These findings highlight critical considerations for developers aiming to implement sustainable LG models in oncology and beyond.
To determine the prevalence of undiagnosed diabetes and identify associated factors using a two-step diagnostic method combining fasting blood sugar with confirmatory glycated haemoglobin A1c (HbA1c) testing among adults 45 years and above in rural Sidama, Ethiopia.
A community-based cross-sectional design was conducted from 1 April to 31 July 2024. Data were collected through a census of adults aged 45 years and above using a pretested WHO-STEPwise questionnaire. Physical and biochemical tests were performed following standard protocols. Data were analysed using Stata V.17.
Selected rural kebeles of Shebedino district, Sidama, Ethiopia.
2875 adults aged 45 years and above.
Undiagnosed diabetes confirmed by HbA1c levels (≥48 mmol/mol or ≥6.5%).
The prevalence of undiagnosed diabetes confirmed by HbA1c was 1.2% (35 of 2871; 95% CI: 0.9% to 1.7%). Previously diagnosed diabetes was found in 0.5% (14 of 2875; 95% CI: 0.3% to 0.8%). The total diabetes prevalence, confirmed by HbA1c or prior diagnosis, was 1.7% (49 of 2871; 95% CI: 1.3% to 2.3%). A total of 1327 out of 2875 (46%) participants were undernourished. Advanced age (β=0.21; 95% CI: 0.08 to 0.32, p=0.001), and estimated annual income (β=0.15; 95% CI: 0.02 to 0.28; p=0.029) were significantly associated with elevated fasting blood sugar levels.
The prevalence of undiagnosed diabetes among rural adult population was low. Older age and higher income were significantly associated with elevated fasting blood sugar. Routine community-based diabetes screening among older population, health education and nutrition-focused interventions are recommended to sustain the low burden and address undernutrition.
Few artificial intelligence (AI) clinical decision support systems (CDSSs) are ever evaluated in practice. Although some signal of clinical effectiveness may be needed to justify AI deployment and testing, such data are typically unavailable in early-stage research. This conundrum is especially relevant in the intensive care unit (ICU), where conditions like sepsis and acute respiratory distress syndrome (ARDS) require high-stakes decisions. Our group developed the AI ventilator assistant (AVA), a novel AI CDSS for patients with sepsis ARDS receiving invasive mechanical ventilation. But the promising results of predictive performance estimates are not sufficient to assess AVA’s clinical safety and appropriateness prior to future evaluation and deployment. Therefore, we propose a Clinician Turing Test as a novel validation approach to determine whether clinicians can distinguish AVA-generated treatment recommendations from those enacted by real human clinicians. If AVA’s recommendations are consistently indistinguishable from those of real clinicians, thereby ‘passing’ this Turing test, this would provide a strong preclinical signal of safety and appropriateness.
This multisite, randomised, electronic, vignette-based Phase 1b study will use a Clinician Turing Test design. We aim to recruit 350 critical care clinicians, including physicians and advanced practice providers from six US hospitals. Participants will review nine clinical vignettes of patients with sepsis and ARDS derived from the Molecular Epidemiology of Severe Sepsis in the ICU cohort and an associated profile of a suggested treatment plan. For each participant–vignette combination, the source of the treatment profile will be randomly assigned (AI-generated by AVA vs the actually enacted treatment from real human clinicians) in a 1:1 allocation. The primary endpoint is the participants’ accuracy in identifying whether a treatment profile was AI-generated or human-generated, assessed using equivalence testing through a mixed-effects logistic regression model with random effects for participants and vignettes. Secondarily, a fitted binary classifier will assess discrimination ability using the C-statistic. Secondary endpoints include clinicians’ perceptions of the safety and appropriateness of the treatment profiles, confidence in distinguishing AI-generated and human-generated recommendations, interest in AI CDSSs for sepsis and ventilator management and the time to complete the survey. This novel Phase 1b design provides preliminary but essential information about an AI CDSS’s clinical appropriateness without the risk or cost of actual deployment, thereby informing decisions about future clinical implementation and evaluation in real clinical environments.
This protocol was approved by the Institutional Review Board of the University of Pennsylvania (Protocol #858201). Results are expected in 2026 and will be submitted for publication in peer-reviewed journals and presented at scientific conferences.
Neurogranin (Ng) has a role in synaptic plasticity and is considered a biomarker of synaptic dysfunction, a process hypothesised to be important in delirium. Few studies examining Ng in delirium exist, with mixed findings. This study aimed to investigate associations between cerebrospinal fluid (CSF) Ng concentrations and delirium in acutely admitted hip fracture patients.
Cross-sectional study.
Acutely admitted orthopaedic patients with hip fracture recruited from four participating hospitals in eastern Norway, representing secondary and tertiary care settings.
This study included 392 hip fracture patients. All admitted hip fracture patients operated in spinal anaesthesia were, regardless of age, considered for inclusion.
An in-house ELISA was used to measure CSF Ng concentration in patients acutely admitted with a hip fracture (n=392). Delirium status was evaluated daily according to The Diagnostic and Statistical Manual of Mental Disorders, Fifth Editions criteria independently by two experienced geriatricians. A value
180 patients (46 %) developed delirium and 70% of these had dementia. CSF Ng concentration did not differ significantly between those with and without delirium (176 pg/mL vs 164 pg/mL), with an estimated difference in medians of 12 (95% CI –5.8 to 29.8), p=0.185. Analyses adjusted for age, gender and dementia status did not show a statistically significant difference in Ng concentrations between the patients.
We did not find an association between delirium and CSF concentrations of Ng. This could imply that synaptic dysfunction and degeneration, involving Ng, are not key processes in the development of delirium. Further studies on other synaptic proteins are warranted to better explore synaptic dysfunction’s potential role in the pathophysiology of delirium.
Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis are sexually transmitted pathogens that are highly prevalent in developing countries and are strongly associated with pregnancy complications. In Chad, screening for these sexually transmitted infections (STIs) in pregnant women is based solely on patient-reported symptoms, even though these infections are frequently asymptomatic. This study aims to determine the prevalence of M. genitalium, C. trachomatis, N. gonorrhoeae and T. vaginalis infections, as well as their associated risk factors.
In this cross-sectional study, we recruited pregnant women attending antenatal clinics at seven hospitals in N’Djamena. Endocervical swabs were collected, and DNA was extracted. Infections were diagnosed using PCR. Risk factors were identified using a structured questionnaire, and associations were assessed using logistic regression.
A total of 525 pregnant women were enrolled, of whom 78.5% resided in urban areas, with a mean age of 25.16±5.54 years. Overall, 23.99% of the study population were diagnosed with at least one STI. The individual prevalence of M. genitalium, N. gonorrhoeae, C. trachomatis and T. vaginalis infections was 13.33%, 5.14%, 0.95% and 4.57%, respectively. Coinfections were low, with M. genitalium-T. vaginalis at 0.95%, M. genitalium-N. gonorrhoeae at 0.38% and other combinations at 0.19% each. Women residing in rural areas had nearly two times the odds of M. genitalium infection compared with urban residents (OR=1.98), indicating a higher risk. AgeM. genitalium infection (OR=1.71) were also associated with significantly increased risk.
This study demonstrates a high prevalence of STIs among pregnant women in Chad, underscoring the need for systematic screening rather than solely relying on syndromic management.
